Abstract
An image display system for viewing an electronic image and an external sight simultaneously, which includes image display units which have an individual controller for outputting image signals to a display unit. The display unit enables a switching operation with a predetermined operation mode from a plurality of operation modes, including a mode for indicating the image signals output from the individual controller. An external control device outputs mode control signals which address the operation mode of the display unit and are received by an external control terminal. A mode exchanging switch specifies a condition of the mode control signal. A detection unit detects whether the external control terminal is connected to a connector capable of outputting a mode control signal. The individual controllers are connected to the external control terminals in turn so as to couple the controllers to the external control device in series. The operation modes can be collectively and forcibly controlled by the individual controllers on the basis of mode control signals received by the external control unit.
